NATO is a mid, long term goal for Ukraine. It’s at least 10 years away and even then, I can’t imagine that anyone in Ukraine would think that US would send troops to protect the country against Russia. (see Budapest Memorandum)
Military co-operation, training, and sharing of military of intelligence is the most that Ukraine can really expect from US and Nato
So you think NATO is fake, and that we will all submit if Russia invades NATO members?
There is opinion war will last for 4 years. I wonder how Ukraine will survive without Russian gas and coal.
